Description

  The present invention relates to a switch and a connection structure thereof.

  As a means to indicate whether the switch operating handle is in the ON position or the OFF position, the ON / OFF nameplate is divided into an ON display and an OFF display above and below the handle handle. A technique for attaching to the front surface is disclosed (Patent Document 1).

  However, the above technique assumes only two positions of the ON position or the OFF position as the handle position, and cannot be applied to a switching switch that can take three handle positions including a neutral position (Patent Document 2). .

  Conventionally, as a means for displaying a handle position in a switching switch that can take three positions including a neutral position, on the upper surface of the housing (upper surface in a state where the handle is mounted upward with respect to the device mounting surface) A display means for forming a label indicating each position or a printing or engraving is formed at a position located on the side of the handle.

  In the conventional switching switch, in order to balance the appearance, the bisector dividing the width direction of the casing into two equal parts and the width direction of the handle are divided into two equal parts when the casing is viewed from above. The bisector is configured to match. Assuming this configuration, if the casing of the switching switch is made compact, the space for forming the display means etc. becomes small and it is difficult to form the display means. There was a problem that it was not preferable.

  As shown in FIGS. 3, 4, and 6, the casing 11 constituting the switching switch is configured by abutting each opening of the box-shaped cases 13 and 14 with one side opened from the width direction of the casing 11. The rivets or fixing screws 15 are inserted and fixed so as to penetrate the width direction of the housing 11. Each box-like case 13, 14 has the same width so that its abutting surface coincides with a bisector (A) that bisects the case 11 in the width direction when the case 11 is viewed from above. Is formed.

  In the case 11 formed by abutting the box-shaped cases 13 and 14 from the width direction of the case 11, there are one electric wire from the input terminal portion 4 and electric wires connected to each of the output terminal portions 2 and 3. Although it is wired and used as a one-pole type switching switch, a plurality of casings 11 can be connected to form a switching switch having a plurality of poles. When connecting a plurality of housings 11, rivets or fixing screws 15 are passed through all cases to engage and fix.

  Each of the box-shaped cases 13 and 14 includes notches 23 and 24 on the upper surface, which are openings 16 through which the shaft portion 28 of the handle 1 is penetrated in a state in which both are abutted.

  As shown in FIG. 5, the notches 23 and 24 have a bisector (B) that bisects the opening 16 when the housing 11 is viewed from above, and a width direction of the housing 11 that is equal to 2 The bisectors (A) to be divided are formed with different lengths in the width direction so as not to coincide with each other. According to the structure, the opening 16 is arranged so as to be offset toward the box-shaped case 13 side in the width direction of the casing 11 when the casing 11 is viewed from the upper surface. It is possible to secure a mounting width for forming the label 100 indicating the position, display means such as printing / engraving, and LED, and even when the housing 11 is made compact, the work of mounting the display means is poor. Therefore, the housing 11 can be made compact.
